How do I use the Enum library in Python?

The Enum library in Python allows you to create enumerations, which are a set of symbolic names bound to unique, constant values. You can use it by importing the Enum class from the enum module.

Can you show me a simple example?

Sure! Here's a basic example:

from enum import Enum

class Color(Enum):
    RED = 1
    GREEN = 2
    BLUE = 3

print(Color.RED)

What if I want to iterate over the Enum members?

You can iterate over the Enum members using a for loop. For example:

for color in Color:
    print(color)

Can I assign string values to the Enum members?

Yes, you can assign string values. Here's how:

class Color(Enum):
    RED = 'red'
    GREEN = 'green'
    BLUE = 'blue'
